WORKING HEAD FOR PUMPS.

Specification of Letters Patent.

Patented Feb. 8, 1916.

T 0 all whom it may concern:

Beit known that I, PHILIP A. MYERS, acitizen of the United States, residing at Ashland, in the county of Ashland and State of Ohio, have invented certain new and useful Improvements in \Vorking Heads for l. umps, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to working heads for -piunps, and more particularly to the frame or structure which supports the pump and its operating mechanism.

The object of the invention is to provide a structure of this kind which can be used with pumping devices of different kinds and of various sizes; and to make the side members of the frame interchangeable.

A further object is to provide a frame of this character which, when assembled, will square itself up, and which will form a very rigid construction when assembled with any of the pumps with which it can be used.

A further object of the invention is to provide, in combination with a frame of this kind, a combined water and air pumping mechanism.

In the accompanying drawings Figure 1.

is a front elevation partly in section'of a working head embodying my invention, and having mounted thereon a combined air and water pumping mechanism; Fig. 2 is a vertical section taken on the line w:0 of Fig. 1, looking in the direction of the arrows Fig. 3 is a transverse sectional view taken on the line y-y of Fig. 1; Fig. l is a front elevation of a working head, showing the frame arranged to receive a double acting pump cylinder which is mounted directly on the frame; Fig. 5 is a front elevation of a working head showing the same supporting a submerged pumping mechanism; Fig. 6 is a vertical sectional view of aworking head mounted upon a sub-base; Fig. 7 is a side/elevation of the same; and Fig. 8 is a side elevation of a working head embodying the invention and comprising a sub-base of a different kind.

In these several drawings I have illustrated a single embodiment of my invention and have shown it arranged for use in conmotion with ipumping devices of various kinds. It will be understood, however, that the frame construction here shown is chosenfor the purpose of illustration only and, further, that the pumping devices shown in the several figures are chosen as illustrative of the various uses to which the frame may be put. In each of these figures the frame comprises two units or side members which are, preferably,- exactly alike and are connected one with the other by detachable connecting members. Each of these frame members comprises a base 1 adapted to support pump operating mecha n1sm,--and having rigidly secured thereto and extending. upwardly rods 2 and brace rods 3, tiese rods being rigidly connected one to the other at their upper ends, preferably by a headblock 4. The guide rods 2 .are preferably vertical, while the brace rods '3 extend at an inclination to the plane of the guide rods, this arrangement being permitted by the difference in the widths ofthe base 1 and the head block 4. These rods may be connected with the base and the head block in any suitable manner. In the present instance the rods are cast in the base and head block so that each frame member constitutes a unitary structure and is completely formed in the foundry. The two side members of the frame being exactly alike, a single pattern will answer for all the castings, and any two frame members can be assembled to make a frame without regard to whether they go on the right or the left hand side. The two frame members which make up the frame are here shown as connected together by tie rods 5 and 6 which extend through apertures in the base and the head block respectively, and are rigidly connected to these parts by means of set screws 7 and 8. 0b viously, by adj'usting'the frames along the tie rods, or by substituting tie rods of different lengths, the distance between the frame members, and consequently the width of the frame, may be varied.

The pumping devices are supported by the guide rods 2 and where the pumping devices comprise a reciprocatory piston the cross head which operates this piston is slidably mounted on the guide rods 2, the length of the guide rods being such as to allow ample space for the reciprocation of the cross head between the tops of the pumping devices and the head blocks. The manner of connecting the pumping devices to the frame members depends upon the naerefrom, guide ture of the pumping devices themselves. In Fig. 1 I have shown a device adapted for connection with a submerged pump, and have provided this device with a water-- cooled air pumping cylinder cooperating with the water pumping mechanism.

The water pumping devices comprise a submerged cylinder of a well known type such as is shown at 9, which is connected by a pipe 10 with the lower end of a cylinder or discharge head 11, which is secured to the side members of the frame. Preferably the' cylinder is provided at its opposite sides with brackets or clamping devices as shown at 12, these clamping devices being preferably formed of separable parts as shown in Fig. '3, so that the cylinder can be very quickly and easily attached to the vertical rods of the frame. A pumping rod 13 extends from the cylinder of the pumping device 9 upward through to the pipe 10, and through the discharge head 11, and is connected at a point above the discharge head with a cross head 14, provided at its oppo site ends with vertical bearings to receive the guide rods 2 and slidably support the cross head on these rods. The cross head is here shown as divided longitudinally on a vertical line to form two parts, the line of division being through the bearings for the rods and the socket for the upper end of the pumping rod. The two parts of the cross head are connected one to the other by bolts 15. This construction enables the cross head to be very quickly and easily attached to the guide rods and the pumping rod, and when so attached forms a very strong durable construction. The cross head is preferably provided at its outer ends with pintles 16 on which are journaled the upper ends of connecting rods 17, the lower ends of which are -mounted on Wrist pins 18, carried by crank wheels 19. The crank wheels 19 are preferably in the form of gears which are mounted on a shaft 20 journaled in bearings 21 formed in the bases of the two side members of the frame. The gears 19 mesh with pinions 22 secured to a shaft 23 journaled in bearings 24 also formed in the base castings 1 of the frame members. The shaft 23 constitutes the driving shaft and may be connected with the source of power in any suitable manner. In the present instance it is shown as provided with a belt wheel 25.

The water is discharged from the forward side of the discharge head 11, through a suitable discharge opening, which is not here shown. Pumps of this type are frequently used in connection with storage tanks which utilize compressed air to force the wateri through the distributing pipes, and consequently, it-is desirable that they should be provided with air pumping devices toenable a proper quantity of air to be forced into the tanks. Some difilculty is experienced in preventing these air pumping devices from overheating, and, in the present construction, I have provided an air pumping cylinder which is so arranged as to be operated from the cross head 14, and as to be constantly surrounded bywater, which will prevent the same from becoming overheated. To this end the discharge head 11 is provided with a laterally extending portion 26 in which is mounted an air pumping cylinder 27 of an exterior diameter somewhat less than the interior diameter of the part 26 of the head. The cylinder 27 is mounted at its upper and lower ends in the upper and lower ends respectively of the discharge head, and is provided with valve controlled inlet and discharge ports 28 and 29 which communicate respectively with the atmosphere and with the discharge head. A piston 30 is mounted in the cylinder 27 .and connected by means of a rod 31 with the cross head 13. The connection between the rod and the cross head is preferably formed by meaiis of a pin 32, the removal of which will disconnect the piston 30 from the cross head, and consequently render the air pumping apparatus inoperative. The air pumping apparatus being constantly surrounded by the water within the head 11, it will be apparent it will not become heated.

In Fig. 4 of the drawings I have illustrated the frame as assembled with a double acting pump, the pumping cylinder 33 being mounted directly upon the guide rods 2 by means of clamping brackets 34. This cylin der has its piston 35 connected with the cross head 14 by a piston rod 36, has at its lower end a screw-threaded boss or tap 37 to receive the suction pipe.

In Fig. 5 of the drawings I have shown the frame as supporting a submerged pump. As here shown a supporting bar 40 is clamped to the rods 2 of the frame and supports pipes 41, which in' turn support a pumping cylinder 42.

In the several forms of the device heretofore described, the bases or feet, as they might be called, of the side-frames are shown as forming the base of the working head, that is, they are the parts which are secured to the platform. However, it is not necessary to an embodiment of the invention that these should constitute the supporting base. It is possible, and under some circumstances might be preferable, to form a separate sup"- porting base and mount the bases of the side frameson the supporting bases. Such a construction is'shown in Figs. 6 and 7 of the drawings. Here the construction of the side members is similar to that heretofore shown, but the bases of the two side members are mounted upon a sub-base 45,'which sub-base is adapted to be mounted upon the platform or other supporting surface.

When a subbase or similar device is used in connection with the side frames, it is not necessary that the lower tie rod 5 should be employed, because the side members are rigidly secured to the sub-base by bolting, or otherwise, and this serves to space the side frame members apart and thus the sub-base constitutes the connecting means between the two side members. When it is desired to vary the distance between the side frame members to accommodate pumping devices of different kinds, this may be doneeither by providing a special base of a difierent width or by changing the position of the bolt holes in the subbase. As shown in this form of the device the working head is provided with a submerged pumping device, the cylinder of which is shown at 48 and is connected, by a connecting pipe 49, with a discharge head 50 which is clamped on to the guide rods 2 in the manner above described. The piston rod for the pumping device, which is shown at 51, extends through the connecting pipe and the discharge head, and is operated in the same manner as the piston rod shown in Fig. 1. In either instance the result is the same. I

In Fig. 8 is shown a. further example of the side frame members mounted upon a sup porting base. In this construction the subbase is of such a character that the pumping devices can be withdrawn without disturbing the base orthe discharge line. Such a base is shown generally at 46 in Fig. 8, and the mechanism is fully shown and described in my Patent No. 928,234, of July 13, 1909. To accommodate the side members to this frame the bases of the two side members, Which are indicated at 47,. are slightly different in shape from those shown in the other drawings, but the guide rods 2 and brace rods 3 are arranged in a similar manner. Y

I have shown one embodiment of my invention, with slight modifications, and have shown the same' as used in connection with several different kinds of pumping devices, out it will beunderstood that the side frame members themselves may be modified in form, and that they may be used in connection with pumping devices of various kinds, either with or without a sub-base or supplemental supporting device. For example, while I prefer to cast one or both of the rods of each frame member in the base and the head, this is not essential, as a rigid construction might be secured in other ways. Further, the character and arrangement of these rods may be varied according to the demands of the particular pumping device with which the invention is employed. In some instances'the vertical. rods may not constitute guide rods, or the rods may not be arranged vertically, or the brace rod may be omitted and bracing action secured in some other manner. Therefore, I do not wish to be limited to the details shown and described for obvious modifications will occur to one skilled in the art.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is
